A 16-year-old male Type A hemophiliac patient has been reported with complaints of defective vision in the right eye (OD), following ocular trauma 9 months back for which he took treatment outside. On examination, he had blood staining of cornea and cataract in his right eye. His vision was perception of light + and projection of rays intact. After hematologist opinion, under peribulbar anesthesia, he underwent penetrating keratoplasty with pupillary membranectomy and cataractous lens removal with posterior chamber intraocular lens implantation under the cover of Factor VIII (antihemophilic factor). On day 21, the best-corrected visual acuity in OD was 6/6P. This case report emphasizes the fact that hemophiliac patients can be operated safely with appropriate hematological support.

| Introduction|| |
Hemophilia A is an X-linked recessive disorder caused by the deficiency of clotting factor VIII characterized by hemorrhages which may occur spontaneously or after trauma [Table 1]. According to the US Centers for the Disease Control and Prevention, hemophilia A occurs in approximately 1 in 5000 live births. Ophthalmic surgeries done on a case of hemophilia are rare. We wish to report the first case of penetrating keratoplasty (PKP) with pupillary membranectomy and cataractous lens removal with posterior chamber intraocular lens implantation in a case of hemophilia A. The surgery was done under the cover of antihemophilic factor.

| Case Report|| |
A 16-year-old male came to our hospital with complaints of defective vision in the right eye (OD). He gave a history of ocular trauma to the right eye 9 months ago for which he took treatment elsewhere. He also gave a history of hemophilia Type A from birth. He had undergone anterior chamber paracentesis for traumatic hyphema elsewhere. Hyphema was not resolving due to hemophiliac status. The patient was managed conservatively with antiglaucoma medications and topical steroids. He had no other significant systemic illness. There was no family history of hemophilia. Examination of the right eye showed blood staining of cornea. Cataract was seen through peripheral clear cornea. The vision was perception of Light + and Projection of rays was intact. Other details were not made out due to blood staining of cornea [Figure 1]. There was no view in the fundus due to blood staining of cornea. Intraocular pressure in OD by Goldmann applanation tonometry was 8 mm Hg. Right eye B scan showed an intact posterior capsule with a clear vitreous cavity, and the retina was attached. Left eye examination was within the normal limits, and the uncorrected visual acuity (UCVA) was 6/6.
Triple procedure was planned. Hematologist opinion was sought. Prothrombin time (PT) was 13 s, activated partial thromboplastin time (aPTT) was 57 s which was prolonged. The activated partial thromboplastin time (PTT) test is used to evaluate the clotting factors of the intrinsic and common pathways of the clotting cascade by measuring the time (in seconds) it takes a clot to form after adding calcium and phospholipid emulsion to a plasma sample. After administering Factor VIII, aPTT becomes normal. The normal range of PT is 12.7–15.4 s, aPTT is 30–40 s, and PTT is 60–70 s. The levels of Factor VIII in blood was 2 % and it was classified as a case of moderate hemophilia A.
Under peribulbar anesthesia, PKP with graft size 8.5 mm over 8.0 mm with pupillary membranectomy and cataractous lens removal with posterior chamber intraocular lens implantation (IOL) was done. Anti-hemophilic factor (AHF, Factor VIII) was given according to hematologist opinion [Table 2]. On post operative day 1, patient had OD vision of 4/60 NIG NIP. On POD 7, patient's UCVA was 6/60, and it improved with pinhole to 6/24. On POD 21 OD best-corrected visual acuity was 6/6P with-1.00Dcyl 140° [Figure 2].

| Discussion|| |
Hemostasis can be achieved in simple bleeding episodes of hemophilia A by the use of fresh frozen or lyophilized plasma. In the event of major trauma or surgical procedures sustained levels of 20%–30% of Factor VIII are necessary to provide hemostasis. Such levels are often impossible to achieve with the use of plasma, and attempts to maintain hemostasis with repeated infusions may lead to congestive heart failure owing to the resulting overexpansion of total plasma volume. Concentrated forms of factor VIII (antihemophilic factor, AHF) provide safer means of Factor VIII replacement. HEMOFIL M, antihemophilic factor (Human), Method M, Monoclonal Purified (Hemophil M, Baxalta US Inc.,1700 Rancho Conejo Boulevard, Thousand Oaks, CA 91320, USA) is a sterile, nonpyrogenic, dried preparation of AHF. The half-life of HEMOFIL M administered to Factor VIII deficient patients has been shown to be 14.8 ± 3.0 h. The expected in vivo peak AHF level expressed as IU/dL of plasma or percentage of normal can be calculated by multiplying the dose administered per kg body weight (IU/kg) by two. This calculation is based on the clinical finding by Abildgaard et al. [Table 3].

Bilateral cataract extraction with peripheral iridectomy without IOL implantation with retrobulbar anesthesia in hemophilia patient was reported by Rothkoff et al. in 1977. In recent times IOL implantation, trabeculectomy and vitrectomy in hemophilia patients were reported by Jijina et al. A case of traumatic hyphema in a patient with severe hemophilia A which was medically managed successfully is also reported by Belviranli et al. Topical deferiprone has been reported to have the potential of speeding up the process of clearance of the blood stain from the cornea while avoiding further surgical complications. A case of delayed suprachoroidal hemorrhage after PKP in a neonate as the first manifestation of hemophilia was also reported. The diagnosis of hemophilia in an elderly patient made after noticing excessive intraoperative bleeding during attempted PKP which was not successful was also reported by Choi et al.
Our case had a successful visual outcome due to preoperative planning. When cornea is removed, mechanical barrier to vitreous expansion is lost. Eyes undergoing PKP have increased risk of expulsive hemorrhage due to sudden globe decompression with an open sky communication with atmosphere. Cataract removal during an open sky procedure is very risky and requires meticulous technique, and it has never been reported before in a hemophilia A patient.
| Conclusion|| |
Hemophilia A patients in case of trauma or spontaneous hemorrhage are mostly managed medically and conservatively. Elective procedures are a rarity due to enigma and fear of complications. This case report emphasizes the fact that elective ophthalmic procedures in hemophilia A patients can be done safely with concentrated forms of Factor VIII and also with careful preoperative planning and coordination with the hematology team.
